IMPROVEIiIE-NT IN HARNESS-CLAMPS. j

Specification forming part of Letters Patent No. 178,072, dated May 30, 1876; application filed April 10, 1876. Y

To all whom it may concern:

Be it known that I, JAMES MeCoRMIeK, of Glidden, Carroll county, Iowa, have invented j a new and ImprovedHarness-Clamp, of which the following is a specification My invention consists of rubber-faced metal plates for attachment to the jaws ot harnessniakers sewing-clamps, to hold the leather to be sewed without injury to it, and at the same time hold it firmly. the said plates being constructed with a groovein the face side, which receives the rubber facing, and holds it secure- 1y without rivets or other fastenings.

llhe drawing is a perspective view ot' my improved jaw-plates. t

A represents the jaw-plates, which are made of thin sheet metal, to attach tol the inner sides of the jaws of the clamp by rivet-s or screws through holes B. C represents the rubber facing to the plates, which are secured by the ianges D E, the flange D being turned over at the top, and E being a strip soldered or brazed onto the inside ofthe plates.

I am aware that it is not new to provide the jaws of a leather-crimping machine with elastic faces; but in said instance strips of rubber -are directly attached to the jaws, and not to a plate provided with means for retaining the rubber or elastic face, and adapted to be attached to the jaws ot' a harness-clamp.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-' The oombinationof the attachable plates.

A, provided with the flanges D E, with the rubber or elastic facing-plates C, as and for the purpose set forth.

JAMES MGGORMlOK.
